For all your gaming related, space exploration needs. Pasted as rich text. June 3, 2022 . The U-2's published maximum altitude is somewhere above 74,000 feet. Note that KSP planes get one substantial speed benefit that's much more pronounced than IRL aircraft, due to the freakishly small planet sizes: they're actually flying at a large fraction of orbital velocity. Control Sensativty for Planes - KSP2 Suggestions and Development Exorcet's Content - Kerbal Space Program Forums Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.. Visit Stack Exchange Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. Put a couple of radial mount parachutes just above the com and add a reaction wheel. Upload or insert images from URL. What determines the maximum altitude a plane can reach? You need to do it with what you've got. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. The idea is to slow the plane to a stall above your landing spot the pop the parachute. If that's all a case of Too Many Words, think of it this way: Suppose you just build a plane the "default" way and don't put any. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. This page was last edited on 22 December 2019, at 20:54. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. You'll notice that usually your prograde marker is slightly below your pitch. The main body is a fuel tank with a Swivel engine at the end. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. Or is it the same for all celestial bodies? It was meant for low altitude flight. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. even stranger is that the surface is textured. Chapter 4. Just sounds like the engines can't get enough air, in KSP high speed also generates air intake so I'm guessing what is happening is that you have the initial speed to get to altitude but the lack of air at altitude is starving the engine resulting in lower speed which further reduces air intake and it cascades until either the engine shuts down or you return to denser atmosphere at a lower altitude. As said above, the Wheesley is specifically designed as a low altitude engine. General Electric F-404 Afterburning Turbofan, Stratus-V Cylindrified Monopropellant Tank, Kerbodyne KR-2L+ "Rhino" Liquid Fuel Engine, LFB KR-1x2 "Twin-Boar" Liquid Fuel Engine, T-1 Toroidal Aerospike "Dart" Liquid Fuel Engine, S1 SRB-KD25k "Kickback" Solid Fuel Booster, IX-6315 "Dawn" Electric Propulsion System, AE-FF1 Airstream Protective Shell (1.25m), AE-FF3 Airstream Protective Shell (3.75m), PB-NUK Radioisotope Thermoelectric Generator, https://wiki.kerbalspaceprogram.com/index.php?title=J-404_%22Panther%22_Afterburning_Turbofan&oldid=95515. 1 1: The basics 2 2: Setting it up 3 3: First flight 4 4: Finishing touches 1: The basics First of all, you're going to need an airplane. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. Of course, this thing has very limited range, speed and acceleration because of the extra weight. - Insane lift to weight didn't help. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? Personally, I don't enjoy survey contracts on Kerbin. Though I'm still working on learning to be better at space planes. It may take some practice to hit your target area this way, because you'll be picking up additional horizontal speed, and thus it's possible to under or overshoot. Create an account to follow your favorite communities and start taking part in conversations. a screenshot of kerbal space program 2. by: lord bird. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. Or you need to put a little bit of angle of incidence in your wings, which will reduce drag since you don't have to pitch the entire plane up, but will be stuck at a fixed angle meaning you'll have to pitch up or down anyway during certain phases of the flight that the plane isn't optimised for. Proceed with caution. Air Flow: Air Flow represents with how much force air passes the turbine (notice: different amounts of air at the same speed equals in different amounts of force!). 2/3 (KSP 1.11.2) - YouTube I break out the Mk2 parts and Panther engines to build a better jet that can go higher and faster. Subscribe -. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). Powered by Invision Community. I've been finding it difficult to build a jet that can fly over 15km alt. As has been said, ISP is nothing to worry about. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. Your link has been automatically embedded. Note that you need to activate the afterburner ("Wet Mode") manually. - "In Space High" means your craft is inside the given Sphere of Influence and above the "Space Border" altitude listed in the Celestial Body Multiplier Matrix. This thread is quite old. It flames out at 25,000. I don't have that other stuff yet. This can make it a good alternative for when you want something that can be controllable and doesn't need excessive heat shielding, but still need to be able to go incredibly fast if necessary, at the expense of increased fuel consumption. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 A little while back I spent a long time trying to circumnavigate Kerbin on the least liquid fuel possible (i posted the record to the sub: 254 units of fuel. It is somewhat slow but very steady in flight. I recommend using a solid rocket booster (or 2 or 5) to you get you the altitude and then launch a small rocket powered plane. Rockets aren t the only way to get to space. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. To reach the initial low Earth orbit of the International Space Stationof 300 km (now 400 km), the delta-v is over six times higher, about 9.4 km/s. With the tanks disconnected that way, the rockets don't leach from the jets. If it's below the cross-hairs, you need a little more AoA. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. Content titles and body; Content titles only You also need to be going very fast to generate adequate lift at high altitudes and unlike the real U-2, you don't need to fear about overspeeding and destroying the plane. Rationale: If that's all a case of Too Many Words, think of it this way: Suppose you just build a plane the "default" way and don't put any AoA at all on the wings. Using very light "engine rich" planes and "reverse swooping" (building velocity at 10km then gently curving up) you can temporarily get above 20km with Wheesely and Juno. How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. Originally posted by lord bird: yep thats right jool has a surface. To get there, you're going to want to climb at the fastest rate you can manage to 18-20 km, at which point you should mostly level off and start accelerating horizontally. Aircraft can be very temperamental to fly, especially on the keyboard. One of my planes is small and agile, and can easily enough glide to a safe landing even if the rockets consume all the fuel. That's all true, but just read the OP: hypersonic appears to be completely out of the question. If it's above the cross-hairs, you need a little less. Any of my search term words; All of my search term words; Find results in. Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. Press question mark to learn the rest of the keyboard shortcuts. These designs are great for getting around Kerbin quickly, but without going orbital. I did some testing and found that the turbojets get the best Isp around 5.2 km altitude, so I was thinking of flying at that altitude. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. Dedicated to the growth and advancement of amateur rocket scientists! It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. Yes. These are the building blocks of solid spaceplane design!Subscribe! It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. I was hoping that the new intakes would give it the added altitude. Best altitude to fly a plane? - Kerbal Space Program - GameFAQs Since gravity is effectively lower, they don't need as much wing area to maintain altitude-- which, in turn, means less drag, which makes for more efficient flight. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Main goals: Auto-trimming. The flight time won't be as long, but you'll be able to fly a "plane" above 18km. Jets drop thrust at higher altitude and speed, but also drop . Satellite Launcher - Kerbal Space Program Wiki Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. The drag differential is because your long-wing layout is using a bunch of struts, and the reason your delta-wing has a higher ceiling is because it has more wing area to provide lift. ksp high altitude plane - digitalidentityorganization.com Kerbal Space Program - Wikipedia Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. Then it is "In Space Low over Mun.". You can spin around the whole world on just fumes. The benefits should be obvious. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! It is usually best for initial designs to be based on logic and real-world physics and then be prepared to experiment with non-logical alternatives for optimisation. High altitude planes - Kerbal Space Program Forums First is thrust; the higher you get, the lower the thrust your engines deliver. Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. All the information you could want to know about science, including the altitudes for each celestial body, and what altitudes a given experiment works on are available at: http://wiki.kerbalspaceprogram.com/wiki/Science. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. How to tell which packages are held back due to phased updates. Paste as plain text instead, But a rockets can do it. But you'll need to unlock: Which cost 300 science. Note: Your post will require moderator approval before it will be visible. The more successful the flights, the more successful the space program is. Basically I can hit a target altitude of 20,000m but can not maintain it. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. The easiest "default" way to build a plane in KSP-- i.e. Double your speed, you need twice as much fuel. alternatively, combine a liquid fuel rocket into your plane. I generally don't fuss with AoI unless I'm making a long range cruiser. I wasn't expecting so many excellent answers! TroubleshootingMechJebPVG - KSP-RO/RP-0 GitHub Wiki Grichman's answer got me in the right direction. Which is capable of high altitude, high speed flight. 101 kPa 1 atm Scale Height 5000 m Atmospheric Height 69 077.553 m 1.010-6 atm Minimum Temprature -40.19 C 232.96 K Maximum Temprature 20 C 293.15 K Oxygen Present Yes Contents 1 Kerbin 2 Topography 3 Kerbal Space Center 4 Atmosphere 4.1 The Troposphere 4.2 The Stratosphere 4.3 The Thermosphere 4.4 The Exosphere 5 The Kerbin System 5.1 The Mun Airplane Plus on SpaceDock Orbiting is the most fun one: the higher the orbit, the less speed you need to maintain to stay in orbit, *and* the less air there is, so that's a double-whammy in terms of reducing fuel consumption. Really. Let me share what I know about jet engines, speed, and efficiency. @SaintWacko's advice is probably the most practical. Most SSTO space planes would be able to accomplish this easily. KSP Career: Episode 13 - High Altitude Surveys - YouTube That annoys me but I can't seem to get a design to make it work.
